Mechanical Engineer

General Galactic designs, builds, and flies advanced spacecraft that redefine what’s possible beyond Earth. Led by former SpaceX, Varda, Impulse, and Relativity engineers, our vision is to dominate cislunar space and build the railway to Mars – expanding access to high-energy orbits and enabling the next generation of missions along the way. Based in Los Angeles, California, we’re leveraging our paradigm-shifting water-based technology to reshape the space domain for good.

Job Description

As a Mechanical Engineer, you will work closely with a focused technical team to design and analyze critical spacecraft structures and systems across our product suite, including Seldon and Dreadnought spacecraft vehicles, Genesis propulsion systems, and more. You will have extreme ownership over your work, move quickly, and operate with high agency. As we grow, there will be opportunities to expand your role with the company.

This is a hands‑on engineering role for someone with experience using fundamentals in mechanical design, mechatronics, robotics, dynamics, materials science, and manufacturing to design and analyze hardware. You will have the opportunity to own major vehicle and ground subsystems. You should be comfortable moving between first‑principles analysis, detailed mechanical design, hardware build, test operations, and post‑test data review.

Responsibilities may include:

Own mechanical system design, component selection, and integration for spacecraft vehicles, propulsion systems, robotics, ground test hardware, and associated hardware

Design and integrate mechatronic systems that support key vehicle functions

Develop and maintain simulations, calculations, and models to guide design decisions

Create CAD models, drawings, interface definitions, assembly procedures, test procedures, and engineering documentation

Plan, execute, and troubleshoot testing of structural systems.

Requirements

Successful applicants should have most of the following:

BS in mechanical engineering, aerospace engineering, or a related technical field

2+ years of experience designing, analyzing, building, or testing aerospace hardware, mechanisms, or related

Strong fundamentals in robotics, dynamics, materials science, and mechanical design

First‑principles approach to problem solving even with incomplete or partial information

Hands‑on experience designing flight or test hardware

Ability to perform practical engineering analysis spanning hand calculations, spreadsheets, Python, MATLAB, CAD, and FEA

Strong mechanical design skills, including CAD, drawings, tolerancing, material selection, manufacturability, assembly, and testability

Experience in a fast‑paced startup environment or similar, with high agency, strong ownership, and willingness to work hands‑on across disciplines

Benefits include medical/vision/dental/PTO/401k/stock options, and more!
